This can also be caused by your provider blocking message sending. I tested the SIM in a regular phone and it could make calls but not send messages.

In my case the reason was that the moden had no IMEI number. It was receiving SMS messages but when I try to send one message, receive CMS ERROR 500.

This is an old thread but for future reference I guess this will be useful:

+CMS ERROR 500 basically refers to unknown error and it is hard to determine, but mostly this may refer to one of the following situations based on Modem or Operator:

  • No or weak network coverage - move modem somewhere with a better signal reception
  • Insufficient SIM card credit - charge SIM
  • International phone number required - send recipient's number to modem with country code

This is an unknown issue. The modem does not specify due to which reason the error occurs. I faced the same issue but when I restarted the system, everything worked fine.
